What is copd?
Chronic obstructive pulmonary disease is an umbrella term for chronic bronchitis and emphysema — long-term lung damage that narrows the airways and destroys air sacs, making breathing progressively harder. Smoking is by far the biggest cause, though occupational dusts, fumes and the rare genetic condition alpha-1 antitrypsin deficiency also contribute. More than a million people in the UK are diagnosed with COPD, mostly over 40, and many more are thought to be undiagnosed.
The condition typically declares itself as breathlessness on exertion, a persistent 'smoker's cough' and recurrent winter chest infections. Diagnosis requires spirometry — a breathing test showing airflow obstruction that does not fully reverse — alongside a chest X-ray to exclude other causes. Flare-ups (exacerbations) punctuate the course and drive much of the harm.
Common symptoms
- Breathlessness, at first on exertion
- A persistent chesty cough with phlegm
- Frequent chest infections, especially in winter
- Wheezing
- Reduced ability to exercise
- Fatigue
- In later stages, weight loss and ankle swelling
How long will you wait?
COPD diagnosis is often delayed by limited access to spirometry in primary care, and a routine respiratory clinic referral typically waits several months, with pulmonary rehabilitation programmes carrying additional waiting lists of months in many areas.
Privately, you can typically see a respiratory consultant within 3–7 days, with full lung function testing and chest imaging completed within 1–2 weeks.
NHS England median referral-to-treatment wait: 12.4 weeks, with 2.5 million people waiting over 18 weeks (May 2026). Individual waits vary by trust and urgency.
Treatment options
- Stopping smoking. The single most effective intervention at any stage — it slows disease progression more than any medicine.
- Inhaled bronchodilators. Long-acting inhalers open the airways and reduce breathlessness, with inhaled steroids added for frequent exacerbators.
- Pulmonary rehabilitation. A structured exercise and education programme that measurably improves breathlessness, stamina and quality of life.
- Vaccinations and exacerbation plans. Flu, COVID-19 and pneumococcal vaccines plus rescue packs of steroids and antibiotics reduce the impact of flare-ups.
- Advanced options. Long-term oxygen for those with low blood oxygen, and lung volume reduction procedures or valves for carefully selected patients.
What does private treatment cost?
As a guide, a private consultation with full lung function testing typically costs £400–£800, with a chest CT scan around £400–£800 if needed.
Does health insurance cover copd?
Be aware that COPD is a chronic condition, so private medical insurance does not cover its long-term management — inhalers, oxygen, pulmonary rehabilitation and routine reviews sit outside cover. PMI's role is mainly in initial diagnosis if symptoms first arise after your policy starts, and some policies cover acute complications. COPD diagnosed before joining will be excluded as pre-existing, and smoking history affects premiums with some insurers.
Frequently asked questions
Is COPD the same as asthma?
No, though they can overlap. Asthma involves variable airway narrowing that typically reverses fully with treatment and often starts young; COPD involves fixed, progressive airflow obstruction, almost always in current or former smokers over 40. The distinction matters because treatments differ. Spirometry before and after bronchodilator medication, alongside your history, allows a specialist to tell them apart — and some people genuinely have features of both.
Can lung damage from COPD be reversed?
The structural damage cannot be undone, but that is not the same as nothing helping. Stopping smoking slows further decline dramatically, inhalers relieve breathlessness, and pulmonary rehabilitation improves exercise capacity and quality of life to a degree that surprises many patients. Treatment aims to keep you active, reduce flare-ups and preserve the lung function you have — started early, it makes a substantial difference.
What is a COPD exacerbation and why does it matter?
An exacerbation is a flare-up — worsening breathlessness, cough and phlegm, often triggered by infection — that goes beyond day-to-day variation. Exacerbations matter because each severe one can accelerate lung function decline and may need hospital admission. Recognising flare-ups early and treating promptly, often with a rescue pack of steroids and antibiotics agreed in advance, limits the damage. Frequent exacerbations should prompt a treatment review.
